2017-08-23bpf/verifier: remove varlen_map_value_access flagEdward Cree2-30/+12
The optimisation it does is broken when the 'new' register value has a variable offset and the 'old' was constant. I broke it with my pointer types unification (see Fixes tag below), before which the 'new' value would have type PTR_TO_MAP_VALUE_ADJ and would thus not compare equal; other changes in that patch mean that its original behaviour (ignore min/max values) cannot be restored. Tests on a sample set of cilium programs show no change in count of processed instructions.

The fact that writes occurred in reaching the continuation state does not screen off its reads from us, because we're not really its parent.

2017-08-23selftests/bpf: add a test for a bug in liveness-based pruningEdward Cree1-0/+16
Writes in straight-line code should not prevent reads from propagating along jumps. With current verifier code, the jump from 3 to 5 does not add a read mark on 3:R0 (because 5:R0 has a write mark), meaning that the jump from 1 to 3 gets pruned as safe even though R0 is NOT_INIT. Verifier output: 0: (61) r2 = *(u32 *)(r1 +0) 1: (35) if r2 >= 0x0 goto pc+1 R1=ctx(id=0,off=0,imm=0) R2=inv(id=0,umax_value=4294967295,var_off=(0x0; 0xffffffff)) R10=fp0 2: (b7) r0 = 0 3: (35) if r2 >= 0x0 goto pc+1 R0=inv0 R1=ctx(id=0,off=0,imm=0) R2=inv(id=0,umax_value=4294967295,var_off=(0x0; 0xffffffff)) R10=fp0 4: (b7) r0 = 0 5: (95) exit from 3 to 5: safe from 1 to 3: safe processed 8 insns, stack depth 0 Signed-off-by: Edward Cree <ecree@solarflare.com> Acked-by: Daniel Borkmann <daniel@iogearbox.net> Acked-by: Alexei Starovoitov <ast@kernel.org> Signed-off-by: David S.

2017-08-23ipv4: do metrics match when looking up and deleting a routeXin Long3-1/+37
Now when ipv4 route inserts a fib_info, it memcmp fib_metrics. It means ipv4 route identifies one route also with metrics. But when removing a route, it tries to find the route without caring about the metrics. It will cause that the route with right metrics can't be removed. Thomas noticed this issue when doing the testing: 1. add: # ip route append 192.168.7.0/24 dev v window 1000 # ip route append 192.168.7.0/24 dev v window 1001 # ip route append 192.168.7.0/24 dev v window 1002 # ip route append 192.168.7.0/24 dev v window 1003 2. delete: # ip route delete 192.168.7.0/24 dev v window 1002 3. show: 192.168.7.0/24 proto boot scope link window 1001 192.168.7.0/24 proto boot scope link window 1002 192.168.7.0/24 proto boot scope link window 1003 The one with window 1002 wasn't deleted but the first one was.

When SOF_TIMESTAMPING_RX_SOFTWARE is enabled for tcp sockets, return the timestamp corresponding to the highest sequence number data returned. Previously the skb->tstamp is overwritten when a TCP packet is placed in the out of order queue. While the packet is in the ooo queue, save the timestamp in the TCB_SKB_CB. This space is shared with the gso_* options which are only used on the tx path, and a previously unused 4 byte hole. When skbs are coalesced either in the sk_receive_queue or the out_of_order_queue always choose the timestamp of the appended skb to maintain the invariant of returning the timestamp of the last byte in the recvmsg buffer.

2017-08-23liquidio: change manner of detecting whether or not NIC firmware is loadedFelix Manlunas3-9/+15
In the NIC firmware, the 1-bit flag indicating "firmware is loaded" moved from SLI_SCRATCH_1 to SLI_SCRATCH_2 (these are Octeon general-purpose scratch registers). Make the PF driver conform to this change. Remove code that sets the "firmware is loaded" flag because it's now the firmware's job to do that. In the code that detects whether or not the firmware is loaded, don't just rely on checking the "firmware is loaded" flag because that may cause a rare false negative. Add code that deduces whether or not the firmware is loaded; that will never give a false negative. Also bump up driver version to match newer NIC firmware.

Drop the goto in xdp_do_generic_redirect() and only return errors directly.

2017-08-22bpf: fix map value attribute for hash of mapsDaniel Borkmann1-13/+17
Currently, iproute2's BPF ELF loader works fine with array of maps when retrieving the fd from a pinned node and doing a selfcheck against the provided map attributes from the object file, but we fail to do the same for hash of maps and thus refuse to get the map from pinned node. Reason is that when allocating hash of maps, fd_htab_map_alloc() will set the value size to sizeof(void *), and any user space map creation requests are forced to set 4 bytes as value size. Thus, selfcheck will complain about exposed 8 bytes on 64 bit archs vs. 4 bytes from object file as value size. Contract is that fdinfo or BPF_MAP_GET_FD_BY_ID returns the value size used to create the map. Fix it by handling it the same way as we do for array of maps, which means that we leave value size at 4 bytes and in the allocation phase round up value size to 8 bytes. alloc_htab_elem() needs an adjustment in order to copy rounded up 8 bytes due to bpf_fd_htab_map_update_elem() calling into htab_map_update_elem() with the pointer of the map pointer as value. Unlike array of maps where we just xchg(), we're using the generic htab_map_update_elem() callback also used from helper calls, which published the key/value already on return, so we need to ensure to memcpy() the right size.
